TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed October 1, 1913. Serial No. 792.701.

'5 the, county of Kings and State oti Xew York. have invented certain new and useful improvements in Type-\Vriting Machines, of which the following is a specification.

My invention ielates to tabulatin mechanism for typewriting machines, and p articularl v to a multiple rack bar of the kind adapted to carry several series of adjust able. stops, enabling the tabulator to be used with a number of different work-forms with little or no readjustment of the stops.

A feature of the invention is the PIO ision of an improved form of rack bar and stops, pern'iitting the stops on each side of the rack bar to he adjusted to any position without possibility of interfering with any of the stops on the other sides'of the rack bar.

A further feature of the invention is the rack to hold a series of adjustable stops,

each stop having a number of counter teeth or pro ect ons to enter between the rack teeth, to firmly hold the stops, and also hav-' mg a tongue projecting from the outer side of the stop to cooperate with a counter stop' on the typewriter. Each column stop carries a spring clip toengzrge flared ends of the rack teeth, each stop being supported solely by theteeth on one side of the rack bar, and not projecting into "space in which the stops on other sides of the rack bar are adjustable.

The rack itself is journaled at or near its ends in blocks, which may be connected by brackets to the typewriter carriage, the rack being located over a series of counter stops on the machine frame, and rotatable to-se.-

. lectively' bring the sets"v of stops intofco+ operative relation to the counter stops! Therack is rotatable to bring any set of} stops into operative position, by means-of a turning head on the end of the rack, yield- 1 against accidental displacement.

ably held by a spring detent. Indices on sa1d head indicate whlch set of steps is in Patented-Nov. 2,191.5.

operative position, and also the sides ofthe rack bar on which the sets of stops are located.

The rack is adjustable longitudinallv by means of an adjusting plate mounted on the bearing block, refinement of adjustment.

being obtained by an adjusting screw threaded into the bearing block'andengaging said plate.

Other features and advanta'ges hereinafter appear.

Figure lis a perspective view of the mechanism. Fig. 2 is a cross sectional view on alarger scale. Fig. 3 is a sectional view showing the right-hand bearing block, and a turning head on the rack bar. Fi 4 is a sectional view showing the left-han bear ing block, and a device for longit-udinally ad usting the rack bar. Fig. 5 is a perspective view of parts shown in Fig. 3.- Fig. 6

is a cross section of a stop. Fig. 7 is a perspective view of thesame. Fig; 8 is a sectional view. at the line (1-4;, Fig. 3, looking in the direction of the arrows. Fig. 9 is a view on the same sectionline, but, looking in the opposite direction.

The rack bar 1 is preferably square in cross section, and is provided on each face with a set of rack teeth 2, the ends '3 of each tooth being inclined outwardly or flared so that the teeth are substantially dovefiled in form. Each adjustable stop comp 'ses a body portion having projecting ri s 5 to enter the .spaces between the rack th 2,

said ribs being separated by spaces 6 subi stantially the width of the teeth. At the side opposite the ribs 5 is a tongue 7 adapt/ ed to project into position to be intercepted by a counter. stop. Each stop 4 is held in position on the rack by. a springclip 8 fprmed with an opening 9 to fit nver the tongue 7 and having ends 10 inclinedwardly to bear against the inclined ended the stop. The'spring clips 8, owing to their j ends 10 being inclined inwardly, are retained on the stops when the latterare re-' moved from the nick: and"seourely held . Each stop is independently attached'tothe. rack bar by first placing it-in an inrack teeth, as indicated at the lowerjpart of Fig. 2, and then moving the sothat one of the ends of the spring clip engages the ends of the teeth and is sprung outward sufiiciently to allow the opposite end 10 to slip overv the corresponding ends of the rack teeth, when the stop may readily be snapped into position. The ends 10 of the'clip engaging the inclined ends 3 of the rack teeth, holdthe stops firmly in position,

I and as thestop has a broad base extending over and engaging a number of rack teeth,

and is firmly held, it forms a solid stop, and

the tendency to tilt or yield when struck by a counter stop is reduced to a minimum, and fcompensatedfor. The strain is valso distributed over ,a number of the rack teeth,

' as'fwell as over the several ribs 5 of the stop.

reference to Fig. 2 it will be noted that leach stop projects-only from one side of the iack,-and also that there is a clearance bethe ends of the stops on adjacent sides tithe rack bar, so that the stops on one rack cannot interfere with the adjustment of the size s on an adjacent rack. Thus, as shown on; ig. 1, and as is also evident from Fig. 2,

" "stopiszma'y be placed on adj acent sides of the Cree 1 "Z The rack bar isprovided with cylindrical ends! or bearin'g"s'pindles 11. and12 journaledin bearing blocks 13 and 14 "respecbar. and in the same transverse plane.

tively, which blocks may be mounted on the typewriter carriage by means of brackets 15 i and" 16. The bracket 16 is adjustably secured to the block 14 by a screw 17 extend= ing through an elongated slot 18 in the bracket and threaded into the block 14. The rack bar isadjustable longitudinally te' bring the stops into exact register with the counter .stops at the normal stopp ng gpositions of the carriage, by'means of an adland having a depending end 20 to enter bejusting plate 19. mounted on the block 13 tween the teeth on the rack bar. The plate 19- is secured in adjusted position by a set -tin an accurate and fine adjustment of the r'ac bar.f A turning head or hand wheel 27 tent 29' projecting '14. The rack teeth bar are designed to receive a separate set of "stops independently adjustable to positlons screw 21 extending through an/ enlarged opening 22 in the plate and threaded into the-bearing block. An adjusting screw 23 threaded-into the block 13 is provided with ahead 24 and a collar 25 to engage a flange 26' 'on the adjusting plate, thereby permitkeyed-to the right-hand spindle 12 on the 'ra'ckbar, has formed on its inner face a series of recesses 28 at angular distances of 'ninety degrees apart and at equal distances from thespin'dle- 12, so that as the rack bar is rotated, the recesses or hollows 28 are brought into position to receive a spring defrom the bearing block oil-each face of the rack corresponding to the columnar rulings of a '1 work-sheet. As the rack bar is rotated, the

flih ml tops aI'QSIICQQS -YBIY brought,

to a dependent position to-cotiperate with a' counter stop'orstops 30. As shown, the stops 30 comprlse a series of decimal tabulator stops mounted in a casing 31 on the vmachine frame and adapted to be'selectivelv projected by the usual mechanism, not shown, into position to intercept the column stops 4 on the rack bar.

The head 27 is preferably provided with a series of figures or other indicating characters 32 to indicatewinch set of column stops 15 in operatlveposltion. A second'set 0f indicating characters 33 may alsobe pro-' vided on the head 27 to indicate the side of the rack bar carrying the stops which are correspondingly designated at 32. 'llhus hforexample, as shown in Fig. 1, the character at 32 on the upper face of the head 27 and indicating the operative set of stops, is the figure 4, which figure in the series of characters is placed on the side carrying saidbe izesorted to within the Ilaving thus described my invention, I
